The valley of balls or Torysh, as it’s called in Kazakh, is located at the Northern tip of the Western Karatau, close to the town of Shetpe in Western Kazakhstan. The area consists of plentiful ball-like rock formations strewn across a wide range of steppe land. The ball’s sizes vary, but most of them are 3 to 4 meters in diameter. So far, the phenomenon is not properly researched, however various geological explanations from mega-spherulites crystalline balls formed in volcanic ash and exposed by weathering to cannonball concretions.
It is believed, that balls are to be concretions a hard, compact mass created by the precipitation of minerals. They’re every so often spherical and generally form in sedimentary rock or soil. In fact, this is not a rare phenomenon, because this type of concretions is found all over the world. So, questions come to mind about what is rare, the size these concretions have reached, as large as those in the valley of balls are found only at some places on planet earth.
The New Zealand famous Moeraki Boulders is another example. Moreover, you can see a massive Lion Rock also called “Sherkala” 332 white and ochre chalk outcrop with various fissures along its rim and more rock formation at its foot. The adjacent places are also the scant ruins of the Silk Road Town Kyzylkala. Source: Atlas Obscura & Amusing Planet
